Hi,

if I session.Save an object, do a session.Delete after that, and do then again the session.Save (all on the same object!) I get this exception if the object has mapped collections with cascade="all-delete-orphan":

Could not save object / no collection snapshot for orphan delete

The problem is, that the collection belonging to the object is still bound to the session. Even a session.Evict on the object does not remove the collection from the session (only the snapshot is removed). But if I Evict an object from the session I want NHibernate to deal my object as transient, so that I can do a Save again.

Background: I'm implementing undo/redo. So I save a reference to the to be deleted object in a command object.

Any hints?


Hibernate version:
1.2.0

Hi,

I opened an issue on Jira some days ago: http://jira.nhibernate.org/browse/NH-1177

It contains a VS2005 solution that reproduces the error.
